IMHO The original blower is a piece o crap. It is an attwood. They make some OK other boat stuff, but the blower, when perfectly functional and brand new, is LOUD. Maybe it moves more air, I didn't check that. I just got sick of listening to it and replaced it with a Rule blower. It was whisper quiet and blew plenty out the cool ass vent thangs that all Epics have on their ass end.
A blower replacement is fully documented on the Maintenance page. My original blower on both my Epics, (yeah) was a noisy but functioning blower. Fpr the 30$ should be the FIRST thing you replace. You need to use it and if it annoys you, you may not. Like a non sporty but safe CGA approved life jacket VS a sporty but don't hold your waterlogged lungs up Shane Bonifay one.
I replaced my blower in my new boat last month after the first five seconds I activated that POS. I installed the same keyless ignition for it that was originally installed on my "00 Epic 22 by the dealer. It is a Mercruiser ignition keypad badass thingamabob that I posted on Wakeworld (like anyone cares;) I like it and it has some cool functions that turn on the blower when you do things like turn on the ignition, turn off the ignition, get below 1200rpm.
The blower is in essentially the same place on a V drive, one screw and the panel on the forward starboard engine compartment comes a' loose. The screw can be accessed from underneath the aft starboard corner cushion. Facing aft, it is inboard, run your finger along the carpet and you will find the stainless bracket. The panel is captured by screws up top (forward starboard lip of the bigass engne side storage compartment. Also the starboard engine panel, it has carpet on one side and really nice perforated fake ass Corinthian leather on the other.
